They watched as he jumped into the passenger seat of a black, two-door Cadillac that had been backed into a parking space next to two trailers on McMillan Street.

The driver, identified by witnesses as a woman with wavy brown hair about 25 to 30 years old, drove south on McMillan, left on Louise Street and then either left or right on Ponce de Leon Boulevard.

Soon after, St. Johns County Sheriff's Office deputies on State Road 16 performed a felony stop on a Cadillac that appeared to be the robbery vehicle. They drove a witness to the scene, but he said the people inside weren't the ones he saw.

The Sheriff's Office assisted further by scanning the surrounding area with its helicopter, Air One.
